This issue may occur if the Outlook registry key is corrupted. When other programs try to use the Outlook Simple MAPI interface, they cannot retrieve the required information from the registry.

You must first remove the corrupted Outlook registry key, and then perform a Detect and Repair operation to have Outlook rebuild the key. To do this, follow these steps:

Click Start, and then click Run.

In the Open box, type regedit, and then press ENTER.

In Registry Editor, locate the following subkey in the registry: HKEY_LOCAL_MACHINE\Software\Clients\Mail\Microsoft Outlook

Select the subkey, and then press DELETE.

Click Yes.

Quit Registry Editor.

Start Outlook.

On the Help menu, click Office Diagnostics.

Follow the instructions on the screen to complete the repair.

Important: Above section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

That did not turn out to be the answer. I found a simpler solution but I am still not impressed with Outlook. Kind of like the comment often heard socially TMI. I installed Outlook in XP and then imported my WAB and messages into outlook 2003 from OE. Copied the appropriate files to to a hold location. Rebooted into W7 and then copied the .pst and other appropriate files into the corresponding directories in W7 version of Outlook. Much difficultiy with UAC and permissions along the way but not part of this issue. I am now happily using Outlook for an email client although I still do not understand why the simplicity of Express was not an included client in W7. I have been in the IT field since the days of EAM equipment in 1958 (50 years). It has been a rule of mine through my early days in punched cards to today to follow the KISS method and it has always worked for me.

I believe you have to download and install Live Mail if you want have an e-mail client. IE8 as installed in Win7 does not have or install an e-mail client. Last e-mail client that came with IE was Outlook Express 6 and it's now obsolete.

It would appear that the question refers to Outlook and not Outlook Express, I do not have an answer either, I have installed Office 2003 with Outlook. I am trying desperately to import my OE old messages etc. Each time it tells me that it can not open the file because some one else is using them. I have copies to Flash Drive, another hard drive etc., all to no avail. Does W7 have some attribute of which I am unaware to prevent this. I have even gone into Permissions and change permissions to allow Everyone Full control on this directory. Still can not open the data files to import into Outlook. Live mail by the ways SUX the big hawsepipe for an email client.

Thanks for this registry setting .... I wasn't sure where to look and then your note helped out. I verified that the registry settings for my mail were different from those set on another similar m/c that had outlook installed too. I did a export
import of those registry settings and viola all was good!!!

Yes - thank you Clinton for the suggestion to export the registry key. I did this from my system w/ a working Outlook 2010. Imported the Registry key into the system that was having issues and everything works! Thanks again, Vicki

I had a similar problem when the trial period for Microsoft(R) Outlook 2010 on my machine ended. I earlier had Office Home and Student 2010. I upgraded to Microsoft(R) Office Home and Busines 2010. When I invoked Outlook 2010, I got the same error message
("There is no email .... control panel"). This problem was rectified by repairing Microsoft Office Home and Student 2010.

Hello, I am having the same error message show up when I hit some people's Contact links on their websites. I am using Yahoo, and there is no Yahoo option for associating certain files. Can this be done when using Yahoo as my email
program? Thanks. Raphael

I had the same type of problem whereby I'd installed Office 2007 on my Windows 8 machine and the Office 365 trial expired. I removed the Office 365, but was then having issues with Office 2007 opening where I was getting the message above.

I followed your instructions and now it's working. Thanks very much for your concise and correct post.

If you are facing the issue even after trying the previous solution, please do the following steps.

go to the "control panel --> Programs --> Default Programs --> set your default programs" and select the "Microsoft Office Outlook" from the Programs list and click on the "Set this program as default" from the right
panel and click ok
